EYEGLASSES.

Specifieation of Letters Patent.

Patented Aug. 6, 1907.

Application filed August 29, serial NO. 332,432.

To all 'whom tt may concem:

Be it known that I, GUs'rAv A. BADER, of Rochester, in the county ofMonroe and State of New York, have invented certain new and usefullmprovements in Eyeglasses; and l do hereby declare the following to bea full, clear, and exact description of the same, reference being had tothe accompanying drawings, forming a part of this specification, and tothe reference numerals marked thereon.

My present invention relates to improvements in inountings foreyeg'lasses, and especially of the type wherein the nose guards, areoperated by a relative horizontal movement of the lenses in the planethereof, and the object of the invention is to provide an improvedmounting of this type wherein the lenses may be easily and convenientlyoperated by means of finger grips adapted to be grasped and operated bythe wearer for producing. the desired movements of the lenses andguards.

To these and other ends the invention consists of certain improvementsand combinations of parts, all as will be hereinafter more fullyexplained, the novel features being pointed out in the claim's at theend of the specification.

In the drawing's: Figure 1 is a front elevation of a mounting foreyeglasses constructed in accordance with my invention. Fig. 2represents a rear elevation of the mounting shown in Fig. 1, and Figs. 3and 4 are plan views showing the relative arrangement of the parts iwhen the nose guards are in open and closed positions respectively. i

Similar reference numerals in the several figures indicate similarparts.

ln Wearing eyeg'lasses of the types wherein a relative movement oradjustment of the lenses serves to operate the nose guards, it isnecessary to grip the lenses with the iingers, and this has provenobjectionable in many instances because the surfaces of the lensesbecome soiled or cloudy so that the vision through the lenses is 40impaired. The present invention avoids this objectionable feature, byproviding suitable finger grips adapted to be manipulated by the fingersof the wearer for effecting the necessary movements of the nose guardsfor applying and removing the eyeglasses.

The mounting shown in the present embodiment of the invention comprisesgenerally, the lenses 1 provided at their inner or proximate edges withsuitable attaching devices 2, the lattcr in the present instance eachhaving a box 3 adapted to receive and secure the shank of the noseguardsl and the attaching arm or lug 5 of the mounting proper. This armsupports a rearwardly-extending bearing (i having' an aperture thereinto slidingly receive a guiding portion 7 of the bridge 8,

the latter, in the present instance being composed of substantiallyrigid material formed into a bowed 01' arched central portion having itsends extending to the rear of the plane of the lenses and th enceextending outwardly behind the corrcsponding lenses and in alinementwith one another. The bearing 6 is attached to a slide 9, the latterextending in a dircctionparallcl to the plane of the lenses, and beingadapted to sli'de through a guiding aperture formed in a bearing lug 10fixed to the outer end of the guiding portion of the bridge, a spring11, prefcrably helical in form and coiled about the guiding portion onthe bridge between the bearing lugs 6 and 10 respectively on the slideand bridge serving to return the nose guards to normal position afterthey have been separated. Toward the rear of the bearing 6 on each guardsupporting slide is pivoted the rear end of an Operating lever 12, thelatter being suitably shaped to provide a finger grip 13 thereonconveniently accessible from the front of the lenses, and atintermediate points on these levers are pivotally connected the links14, and the latter are connected at their outer ends to the bridgepreferably by the projection 15 formed on the bearing lug 10.

In eyeglasses constructed in accordance with my present invention, it isunnecessary to grasp the lenses by the fingers in order to fit theeyeglasses to, 01' remove them from the nose, as the desired operationof the nose guards may be conveniently accomplished by means of theOperating levers, the finger grips on the latter being pressed togetherby the fingers when it is desirable to separate the guards, and theSprings confined between the bearing lugs of the bridge and slidesrespectively, serving to automatically engage the nose guards With thewearer's nose when the finger grips are released from the fingers.

A mounting of the kind shown provides a connection for the lenses thatwill prevent relative Vertical tilting or rotation of the lenses, sothat a mounting of this kind may be used in connection with cylindricallenses prescribed for the correction of astigmatism, and the novelarrangement of the parts avoids a conspcuous appearance of the mountingas viewed from the front.

I claim as my invention:

1. In eyeglasses, the combination with the lenses, nose guards attachedthereto` and a bridge having sliding' connections with the lenses forpermitting; relative horizontal movement thereof, of finger gripsmovable relntively to the lenses for Operating them to prodnce the(lesired moveinent of the nose gnards.

In eyeg'lasses, the combination with the lenses, nose e'ufu'ds attnchedthereto, and a bridge having a sliding connection with the lenses forpermitting relative separation ol' the lenses, ol' opernting' leversconnected to the nose ;ruin-ds and having' finger grips thereon by meansof which the guards may be udjusted.

3. In eyegiasses, the combination with the lenses, and l arranged on theslides and guiding portions of the bridge nose guards attached thereto,ot' a bridge having horizontally-extending gniding portions on its ends,sliding connections between the guiding` portions On the bridge and thelenses, and Operating Ievers connected to the ienses for Operating them.

4. In cyeglasses, the combination with the len'ses, and nose guardsattached thereto, of av bridge having a sliding connection with thelenses, and an Operating lever having operative connections between thebridge and a lens.

In eyeglasses, the combination with the lenses, nOse guards attachedthereto, and siides secured to the lenses, of a bridge having gnidingportions thereon corresponding to said slides, bearing lugs arranged onthe slides and the gniding portions Of the bridge respectively, springsarranged between said bearing lngs and normally Operating tO proximatethe nose guards, and iinger grips Operatively connected to the noseguards for Operating them.

(i. In eyeglasses, the combination with the lenses and nose guards, anda bridge having sliding connection with the lenses, of Operating leverseach connected respectively with the bridge and the ienses and havingfinger grips tor operating them.

7. In eyeglasses, the combination with the lenses, attachim),l devicesthereon having horizontally-extending slides secnrcd thereto, noseguards attaehed to the ienses, a bridge having hori'Aontal guidingpoi'tions thereon and bearings and forming a sliding connection betweenthe latter and the lcnses, of Operating levers pivOted at their rearends to the bearing on the slide and having inger grips formed on theirforward ends, and links pivotally attached to the bearings on the bridgeand connected to intermediate portions of the Operating ievers.

8. In eyeglasses, the combination with the lenses having suitableattaching devices at their proxirnate edges, nOse guards connected tosaid attaching devices, and a bridge having a sliding connection withthe lenses in substantially the same horizontal plane with the attachingdevices, of fing'er grips operatively connected to the lensesl andarranged in substantially the same horizontal plane with the attachingdevices.

9. In eyeglasses, the combination with the lenses, nose guards, and abridge having sliding connections with the lenses arranged snbstantiallyin the plane of the major axes of the lenses, of Operating levers havingsuitable operating connections between the lenses and the bridge, saidlevers being arranged substantially in the same horizontal Diane withthe sliding' connectionsA GUSTAV A.
